Nookdevs went down years and years ago unfortunately. I need some guidance if anyone here still remembers.
I have a later revision Nook classic, one that does not have a removable emmc card. It is on 1.4.3 right now.
It was already rooted, but recently when I picked it up and tried to wake it from sleep mode, it decided to reinstall it's own firmware. So it's unrooted as far as I can tell and I don't know where to begin. It's been many years since I looked into this.
I have found this:

But I don't know if that is the method I used last time. I do not remember permanently damaging my browser to get root.
